Why don't you get sick each time you drink orange juice?
Actually, it is a myth that drinking orange juice prevents
sickness, but it's a myth with some truth to it. Orange juice is
high in vitamin C. This vitamin is very important to the immune
system in fighting off disease. So, while drinking orange juice
probably will not prevent every cold or case of the flu, it will
definitely give you the vitamin C that helps your body to resist
the illness, and it may even speed recovery along.
That said, if you are asking whether drinking orange juice can
make you sick, there are some people who find orange juice
difficult to digest because it is acidic. If you are someone who
gets heartburn after drinking orange juice, you may want to seek
another kind of juice that agrees with your digestive system
better.
